I cook ALOT and as a consequence I burn through appliances and tools faster than most people.  I use my immersion blenders for cooking and I buy a extra for soap making.  I have burned through 6 of them to date.  This one i expect will last longer because it is better built than any other I've bought previously.  Solid with no gaps, heavy duty,  speed control,  and I'm loving the flat head (easier to clean!).
